F ig. 10 is an elevation of the upper part shown b Fig. 9 as seen in the direction looking rom left to right of said figure.

Fig. 11' is a plan of the parts shown by Fig; 9;

Fig. 12 is a plan of the parts below line CD of Fig- 9.

Figs. 8 to 12 inclusive are drawn to an en- A indicates the end frame of the machine and B B the upper and lower longitudinal rails forming the framework of the machine in known manner.

In carrying our invention into efiect in connection with a cap spinning machine as is herein illustrated by the drawings, we make use of the usual sliding bifurcated members 2 which lay-hold-ofi the upper ends of the caps 3 to retain same when the spindles 9 are removed, but in accordance with our invention we pivot these bifurcated members 2 upon a rod 4 which extends from end to end of the machine in order to be supported by radial arms 5 which extend from another rod or shaft 6. i

I This rod or shaft 6 is arranged to be 0'scilla-ted by hand leveror hand wheel devices in well known manner in order that by the oscillations of this rodi6 the bifurcated members 2 may be moved from their inoperative positions-shown by Fig. 2 to their forward positions where they lay-hold-of the cap?) as shown by Fig. 3.

As will be observed'the bifurcated members 2 rest and slide over the upper surface of the longitudinal binding rail B over which they are guided by a covering rail 7 shown ,by'theseveral drawings, by which arrangement the bifurcated members 2 may occupy comparatively little space and may be cheaply produced whilewe have found them to carry out their functions efficiently. In conjunction with the devicesdescribed wemake use of the usual spindle rail 8 which extends from end to end ofthe machine and has fixed upon it the series of s dies 9 Eatioiiary during the spinning process. The longitudinal spindle rail 8 is arranged to slide and to be guided by the framework of the machine in such a vertical path that it may be lowered from its operating position shown by Fig. 2 down to its lowest position as shown by Fig. 3 for the purpose hereinaliter explained, and according to our invention we effect this rising and falling movement of the spindle rail 8 by the employment of vertical screws 10 which are supported at their lower ends by the rail B while their upper ends are made to take through a screwed nut 11 liXed upon the rail 8.

The number of screws 19 is arranged to be in accordance with. the length of the rail 8, the long-er such rail 8 is so is the number of screws 10 increased. Upon the lower end of each screw 10 is fixed a bevel wheel 12 which nears or meshes with another bevel wheel 13 fixed to a pinion which is mounted upon a stud 14 fixed to a bracket 1 1. Each screw 10 has its bevel 12 meshing with the said corresponding wheel 13 mounted as described according; to the length of the rail 8 and the number or" screws required to operate same. Each pinion 15 is operated by its respective drivingwheel 16 fixed upon a shaft 17 which extends lengthwise the machine. The shaft 17 is actuated by a hand wheel 18.

heel 18 the shaft 17 is rotated and the eral wheels 16 wiich engage with the pinions 15 are also rotated and as these pin'ions 15 are coupled to the bevel wheels 13 which me h with the bevel wheels 12 rotary motion in one direction or the other direction; as may be desired is given to the screws 10 thus as said screws 10 are rotated the rail 8 and liS spindles 9 may be caused to descend from their highest to their lowest or from the lowest to their highest position as will be understood.

In combination with the apparatus described we now make use 01 a plate or rail. 19 which extends lengthwise the machine so that the metal tubes 19 (see Figs 91 10, 11 and 12} upon which the bobbins 20 ar placed for spinning and winding in known aanner. may be mounted to revolve upon said rail 19 thus these tubes 19 and the bobbins 20 which thev support, are separate from the driving wharles 21 which revolve freely upon the spindles 9 which take through said wharles or pulleys 21 as well through the tubes 19 and their bobbins 20, so that they may be raisedand lowered by the ordinary litter rail 22 as will be un derstood. In other words althouoh the rails 22 and 19 support the wharles 21 and the tubes 19 carrying the bobbins 20 separately, vet when the lifter rod 23 (which is the i cld and well known litter or poker rod and the attendant operating this hand is operated in the old and well known manner) rises and descends it carries with it both of the rails 22 and 19 and the wharles 21 and the tubes 19" with'their bobbins 20 in their said vertical paths at which time the several parts carried by the said two rails 22 and 19 will slide over the spindles 9 also in well known manner.

The plate 19 and supports for the bobbins 20 are duplicated so that we have two of such plat-es 19 and their parts which support the bobbins 20 in order that when one is in use the other may be out of use as is hereinafter explained-v while when the one which is in use has had the bobbins which it operates supplied with their full quantity of yarns or threads 21, the rail 19 may be removed and the other rail 19 may be made to take its place in which case said rail 19 will have its bobbins 2O empty prior to being placed in position ready for the spinning operations to be recommenced is shown by Fig. 6.

As means for layinghold of or receiving and supporting the tube carrying rail 19 when same has to be removed from the position it occupies upon the spindles 9 to the position shown at 19 in front of the machine we arrange vertical racks 26 which are suiiicient in number to meet the requirements and which are situated in front of the machine so that a series of said racks 26 may carry at their upper ends radial arms 27 upon which projecting pins 28 are fixed in order that when said racks 26 are raised the radial arms 27 may be turned from the position shown by the plan at into the position shown by Figs. 2, 3 and 7 where the said pins 28 are in alignment with openings 19 made in the plate 19 and which will pas-s through notches 22 made in'the litter plate 22 in order that when the rail 8 is lowered by its screws 10, in manner hereinhetore described, the rail 22 will pass the outer end of the arms 27 and pins 28 and will allow the rail 19 to descend. so that openings 19 in said rail 19 will take over the pins 28 when in the position shown by Fig, 3.

At this time the rail 22 will descend alonw with the rail 8 into a lower pos n so t the upper ends of the s indles 9 are bro i beneath the arms 27. thus by the .ndant rotating' the shaft 29 by means of the hand wheel 30 said hand wheel w ll operate pinions 31 which mesh with the racks 26 while other pinions 31 mesh (at the opposite side) with the racks 32 whi h are same in number as the racks 26 throughout he length of the machine, consequ ntly when the racks 26 rise the racks 32 descend.

[as the attendant revolves the shaft made to cause the racks 26 to descend and in descending: (bv reason ot radial pin 33 which is fixed to the rack 26 being made to lli) 29 bv the hand wheel 30 the pinion 31 may be the shaft 29)- meshing with' the additional racks 32, as the racks 26' are causedto de- -scend by the actionsot sa'idshaft 29, the

racks 32 will becaused to rise "(by the actions eXt-endthrough a ca-in slot 84 made-in a tube 3 L) a swivelling action 1S transmitted to the 'rack 26 to cause it to revolve and-"carrywith it'the arms 27 so as to-removethe pins '28 from the position in alignmentwitli the spindles-9mm the position shownby Figs.

at, and 6. "Here it will have brought itsrail 19 clear of all the parts which arein alignment witlithe spindles 9-in order that said spindles may -'befreely raised as is hereinafter described.

"By additional pinions 31 (also fixed'on of the pinions 31 and whenthe pins 32,

which extend from said racks 32 through longitudinal slots made in the tubes 36,

"reach the cam slots 36 tnen swivellinginotion will be transmittedto theracks 32 so that they will bring their radialarms 37 from the'positioirshown in Fig; 4yinto the position shown by Fig. 6' where the empty bobbins 2O which are carried bythe rail 19 are brought into alignment with the spindles 9 in whichposition the racks 26 and their arms 27 with their rail 19 will liavedescendedinto the position shown by Fig. 6 with the .full bobbins carryingwith "them the extendingthreads 24L. WVlien the A rail 19 was being moved horizontally over the top of the full bobbins 20 shown'by Fig.

' 6''the edge of the rail 19 will have carried with it the threads 24 so that these threads 24iare in contact with the peripheral edges of the discs l0 fixedupon the lower ends after explained. I

As is hereinbefore describedwhen the racks 26 and 32 have been operated bypinions carried bythe' shaft 29 to place the empty bobbins 20 in the position shown by Fig. 6 in order to carry out the readjustment of the parts ready for the spinning operations to recommence as is hereinafterexplained, the racks 26 and 32 are againadiustcd so that the arms 37 "are brought back to their positions shown by Fig. 4 and the arms 27 are then raised to carry the fplate 19 and its tullbobbins highe'nough to'permit the attendant to bring-arms having" projecting pins 50 beneath said plate 19.

After these arms 50have thus receivedthe plate 19 the attendant'may' then move them' to carry this latter and its fullbobbins into the position shown by Fig. 7. The full bobbins areretained .in this position until removed by theattendant and-thearms 27" remain in the position also shown by Fig. 7 during-thespinning operations as above stated.

The-"arms -50 are fixed upon a shaft 51 *which extends lengthwise the machine to 'ca'rry'the' whole series of said arms 50; and this shaltolis -'actuated by-a handle 52 shown by Fig. 1.

As ishereinbefore stated the tubes 19 are separateand detachable from engagement with the w-harles or driving pulleys 21 and toen'a ble the one to engage'with the other a disc 41 fixed to the lower end of tube 19 has an engaging tooth or teeth 41 which -will -'enga-ge with a corresponding tooth 21 on thewharle 21 in order that the motions-of the driving tape 21 which efiiect the rotarymotions of the Wharle 21 may also through the coupling teeth ll,

4P transmit motion to the tubes 19 and the bobbins which they carry.

1T0 the-rear ot the plate or rail-19 is fixed a'notc'hed cutter bar 43' the notches 42 in which are in such positions that by the disc 10' carrying thethr'ead 24: during its rotary motions, said thread will be Wound around the bobbin tube 19 for about one revolution and then will be severed by belig' brought in contact" with the sharpened edge42t of the cutter bar-42, with the result hereinafter described.

'The'actions of the parts hereinafter described are as "follows "On the spinning operations being com- Q'pleted'with the full bobbins 2O ready to be ieii'ioredti'oiii the spinning spindles in order to enable the empty bobbins 20 to take their placesi themotions of the machine are arrested. The attendant then actuates the bifurcated pieces 2"'and-nioves them forward in manner described to engage with t-hecaps B" as shown by Figs. 3, 5 and 6, so that the said caps 3-will be supported by said bifurcations in manner well known. He will then operate the well-known devices for lowering the poker rods 23 in order that the lifterrail-22"and the additional rail 19 may "belowered into their lowest positions shown by Figs 3', 5 and 6.

During said operations the arms 27 carried by'the racks 26 will be in their normal pos i-tionshown by Fig. 3 (which position they are allowed to assume during all the spinning operations) so that they will there receivethe'plate19 and the parts including 'the' full bobbins-which it carries. The attendant will then actuate the hand wheel 18 and cause (through the spur wheels and devices wliicharekmo'ved by it) the screws 10 torotfate in order that these latter will lower therail-8*from the-position shown by Figs.

land 2 -to-ithe positionshown by Figs. 3,

5, and-6.

'- On descending into this position the rail 22 and the wha'rles it supports, descend into their position as shown by Figs. 3, 5 and 6. During the descending of the plates 22 and i9 above described (by reason of the plate 22 moving past the horizontal arms 27) the plate 19 will also descend so that the openings therein will take over the pins 28 on the arms 27. The attendant may then again ac tuate the hand wheel 30 in order to cause the racks 526 to descend at which time the actions or the cam slots 3?; upon the racks 26 will cause same to rotate and carry the rail it) entirely clear and out or alignment with the spindles 9 so that the said rail 19 may descend into the position shown by 5, carrying with it full bobbins 20.

As the full bobbins are thus lowered and before reaching their very lowest positions the racks will have raised the plate 19 so that it reaches its highe t position and on approaching s h st po ition the ac tions of the cam slots 1" as above described, cause the arms 37 to swivel horizontally to bring their rail 19 into the position previously occupied by the rail 19 and as is shown by Fig. 6. This rail 19 will have thus brought the empty bobbins 20 into the said position in order that the attendant may then actuate the hand wheel 18 and cause the rail 8 to rise to its normal position in which position it is adjusted and in which position the ordinary poker rods will have also been adjusted so that the empty bobbins 2O are made to take within the caps 3 while the spindles 9 also w'll be raised to take into the upper ends of said caps 23 thus the bifurcated members 2 may be withdrawn from supporting said caps 3.

When these parts are thus readjusted in position the attendant may then start the machine into its spinning operations and the actions or the disc 40 upon the threads 24 will have the effect of winding said threads for one revolution around the empty bobbins 20* and severing same so that the spinning operations may continue.
